Description

Technical Field

[0001] This invention relates to the field of insect-attracting technology, specifically an insect-attracting device. Background Technology

[0002] Pest control remains a crucial and ongoing challenge in agricultural production. Physical control methods are gaining increasing attention due to their environmental friendliness, lack of residue, and absence of resistance. Among the various physical control technologies, light trapping, which utilizes insect phototaxis, is particularly widely used. This technology emits light sources of specific wavelengths (such as ultraviolet light) to simulate natural light waves that insects readily recognize for flight or foraging, thereby attracting specific pests to the vicinity of the device and achieving the purpose of trapping or killing them. This effectively reduces the pest population in the target area, making it a key green control method.

[0003] Currently, most mainstream light-based insect traps on the market employ a high-voltage electric grid as a final treatment method to kill insects. Specifically, these devices typically deploy a high-voltage electric grid directly around the light source. When insects attracted by the light come into contact with the grid, they are instantly killed by the high-voltage current. While this method can directly and effectively kill pests, the exposed high-voltage grid carries thousands of volts during operation. Although the current is relatively small, it still poses a potential risk of electric shock to humans (especially operators or curious children) and non-target animals (such as poultry, birds, or beneficial insects). This danger is particularly pronounced in humid and rainy environments. Therefore, this existing insect control method, which relies on an external high-voltage electric grid, needs improvement in terms of safety, applicability, and ease of maintenance. Summary of the Invention

[0004] The present invention provides an insect-attracting device that solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An insect-attracting device includes a main trapping chamber with a support assembly on its outer wall, and further includes an insect-collecting mechanism and an insect-attracting mechanism. The insect-attracting mechanism includes a conical head disposed inside the main trapping chamber, with the tip of the head pointing away from the ground. A drive shaft is rotatably connected to the tip of the conical head, and an insect-attracting light column is fixedly connected to the end of the drive shaft. An insect-scraping paddle is disposed outside the light column, rotating synchronously with the drive shaft. An insect-collecting conduit is sleeved on the outside of the insect-scraping paddle, with one end of the conduit near the ground fixedly connected to the main trapping chamber. The interior of the conduit communicates with the interior of the main trapping chamber. When the drive shaft rotates, the insect-scraping paddle drives the gas inside the conduit to move towards the interior of the main trapping chamber. The outer edge of the insect-scraping paddle is in clearance fit with the inner wall of the conduit. The insect-collecting mechanism includes an insect-collecting container disposed on the ground-facing side of the main trapping chamber, communicating with the interior of the main trapping chamber.

[0007] In a preferred embodiment of the present invention, a conical insect-guiding opening is provided at the end of the attracting conduit away from the ground, and a light-amplifying component is provided on the side of the conical insect-guiding opening away from the ground to reflect the light emitted by the insect-attracting light column into a horizontal state. The light-amplifying component includes a support rod disposed inside the conical insect-guiding opening, an insect-collecting funnel disposed at the end of the support rod, and reflectors for reflecting light disposed on both sides of the insect-collecting funnel.

[0008] As a preferred embodiment of the present invention, the insect collecting jar is provided with a triangular plate inside, a pheromone emitter is provided on the triangular plate, an attractant is placed inside the pheromone emitter, an air inlet is provided on the side wall of the insect collecting jar, an odor diffusion hole is provided at the end of the main trapping chamber away from the ground, and an airflow guide shroud is provided on the outer edge of the conical head to drive the airflow toward the odor diffusion hole.

[0009] As a preferred embodiment of the present invention, the conical head has a hollow structure, and a motor support plate is provided inside the conical head. A rotary motor is provided on the motor support plate, and the output shaft of the rotary motor is fixedly connected to the end of the drive shaft.

[0010] In a preferred embodiment of the present invention, the insect collecting container is provided with a threaded ring at its end, and a threaded sleeve that is threadedly connected to the threaded ring is provided at the end of the main trapping cavity near the ground. The inner wall of the insect collecting container is provided with a protruding beam, the end of which is rotatably connected to a rotating seat. The rotating seat is rotatably connected to an openable / closable baffle. A torsion spring is provided inside the rotating seat to drive the openable / closable baffle to a horizontal position. A pressure ring that cooperates with the openable / closable baffle is provided on the side of the main trapping cavity near the insect collecting container. When the openable / closable baffle contacts the pressure ring, it rotates to a vertical position. A clearance groove that cooperates with the openable / closable baffle is provided between the pressure ring and the main trapping cavity.

[0011] As a preferred embodiment of the present invention, the support assembly includes a support frame fixedly connected to the main trapping cavity, a limiting sleeve rotatably connected to the end of the support frame, a limiting pin slidably connected to the side of the limiting sleeve away from the support frame, and a locking nut provided at the end of the limiting sleeve to limit the extension length of the limiting pin.

[0012] As a preferred embodiment of the present invention, a bracket is provided on the outer side of the drive shaft, and a scraper blade is fixedly connected to the end of the bracket away from the ground. A scraper that moves along the surface of the conical head is provided on the side of the bracket closer to the ground.

[0013] The present invention has the following advantages:

[0014] 1. Achieves highly efficient synergy between light and odor attractants: This invention combines the insect-attracting light column with a pheromone emitter, utilizing both light and attractants as insect-attracting sources, significantly enhancing the insect-attracting effect. The rotating insect-scraping paddle creates a directional airflow within the main trapping chamber and the trapping conduit. This airflow continuously discharges attractant molecules volatilized from the pheromone emitter through the odor diffusion holes and diffuses them into the surrounding environment, thereby expanding the odor's effective range. Combined with the multi-angle radiating insect-attracting light, this achieves highly efficient synergy between visual and olfactory insect-attracting factors, improving the device's overall trapping capability.

[0015] 2. An active and reliable insect capture and guidance mechanism is provided: The rotational motion of the insect-scraping paddle constitutes the core capture and transport mechanism of this device. Firstly, the scraping paddle actively scrapes and pushes insects that have crawled into the trapping tube downwards, preventing their escape and ultimately leading them into the main trapping chamber. Secondly, the downward airflow generated by the rotating paddle further hinders the insects' upward escape and assists in the diffusion of the attractant. Under the continuous action of the scraping paddle, the captured insects are eventually guided into the insect collection container through the gap between the conical head and the main trapping chamber, completing the collection process. This actively guided, closed-loop capture path significantly improves the insect capture rate and reliability.

[0016] 3. Ensures safety and convenience of operation: All moving parts of this device are enclosed within the main trapping chamber and the trapping conduit, with no external rotating mechanisms or exposed high-pressure components, eliminating safety hazards to humans and animals. Insect collection is achieved simply by unscrewing the insect collection container. During this process, the openable / closed baffle automatically rotates to a horizontal position, promptly sealing the passage and effectively preventing insects from escaping during disassembly. This design makes collection simpler, safer, and more hygienic, facilitating subsequent processing or research of the captured insects. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] In one embodiment, see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5An insect-attracting device includes a main trapping cavity 1, with a support component 2 provided on the outer wall of the main trapping cavity 1. Three support components 2 are symmetrically arranged along the central circumference of the main trapping cavity 1. The support components 2 support the entire insect-attracting device to maintain a vertical state. The device also includes an insect-collecting mechanism 3 and an insect-attracting mechanism 4.

[0031] The insect-attracting mechanism 4 includes a conical head 15 disposed inside the main trapping chamber 1. The conical head 15 has a conical structure, and its tip is vertically upward. A vertically arranged drive shaft 19 is rotatably connected to the upper end of the conical head 15. An insect-attracting light column 12 is disposed at the upper end of the drive shaft 19. The insect-attracting light column 12 can generate light waves of a specific frequency to attract insects. A support 18 is disposed in the middle of the drive shaft 19, and a scraper 17 is disposed at the lower end of the support 18. The scraper 17 rotates along the upper surface of the conical head 15, thereby driving away the insects lying on the conical head 15 to the outside, so that the insects eventually crawl down through the gap between the conical head 15 and the main trapping chamber 1. Two to three insect-scraping blades 11 are disposed symmetrically with respect to the center circumference of the drive shaft 19. A trapping tube 9 is fitted around the insect-attracting light column 12 and around the insect-scraping paddle 11. The trapping tube 9 is a vertical tubular structure. The outer side of the insect-scraping paddle 11 slides along the inner wall of the trapping tube 9. The outer edge of the insect-scraping paddle 11 is in clearance fit with the inner wall of the trapping tube 9. When the drive shaft 19 drives the insect-scraping paddle 11 to rotate, on the one hand, the insect-scraping paddle 11 can push the gas inside the trapping tube 9 downward, thereby achieving a fan-like air supply effect. On the other hand, the outer side of the insect-scraping paddle 11 rotates along the inner wall of the trapping tube 9. At this time, the insects crawling along the inner wall of the trapping tube 9 will be pushed downward by the insect-scraping paddle 11, thereby pushing the insects into the interior of the main trapping cavity 1. The lower end of the trapping tube 9 is fixed to the middle of the upper end of the main trapping cavity 1, and the interior of the trapping tube 9 is in communication with the interior of the main trapping cavity 1.

[0032] The insect collection mechanism 3 includes an insect collection container 24 located below the main trapping chamber 1. The insect collection container 24 is an open container at the top. The upper end of the insect collection container 24 is detachably connected to the lower end of the main trapping chamber 1. The inner diameter of the main trapping chamber 1 is larger than the outer diameter of the conical head 15. The gap between the main trapping chamber 1 and the conical head 15 is larger than the volume of the insect. A fixing rod 21 is provided on the inner wall of the main trapping chamber 1. The fixing rod 21 is fixedly connected to the conical head 15, so that the conical head 15 is located at the center of the main trapping chamber 1. Therefore, when the insect crawls down through the gap between the main trapping chamber 1 and the conical head 15, the insect will crawl into the inside of the insect collection container 24 and be stored in the insect collection container 24. After the entire device has been working for a period of time, the operator can remove the insect collection container 24 and take out the insects inside the insect collection container 24.

[0033] In one instance of this embodiment, please refer to Figures 2-5 The upper end of the attracting conduit 9 is provided with a conical insect guide opening 10. The diameter of the conical insect guide opening 10 gradually decreases from top to bottom. Above the conical insect guide opening 10, a light amplification component 8 is provided. The light amplification component 8 can reflect the upward light emitted by the insect attracting light column 12 into a horizontal state, so that the entire insect attracting device can diffuse the light outward and better attract nearby insects. The light-amplifying component 8 includes a support rod 5 disposed inside the conical insect-guiding opening 10. The lower end of the support rod 5 is fixedly connected to the inner wall of the conical insect-guiding opening 10, and the upper end of the support rod 5 is fixedly connected to the lower end of the insect-collecting funnel 6. The insect-collecting funnel 6 is a vertically downward funnel shape. Reflective plates 7 are attached to both the inner and outer walls of the insect-collecting funnel 6. Therefore, the light emitted by the insect-attracting light column 12 is reflected by the reflective plate 7 on the outer wall of the insect-collecting funnel 6, resulting in horizontal light rays pointing outward. At the same time, the light emitted by the insect-attracting light column 12 is reflected by the reflective plate 7 on the inner wall of the insect-collecting funnel 6, resulting in upward light rays, thereby increasing the radiation range of the light. Furthermore, the insect-collecting funnel 6 is designed as a funnel shape that extends vertically through the insects. On the one hand, this increases the light angle, and on the other hand, insects can climb down the inner and outer walls of the insect-collecting funnel 6, so that all insects can eventually climb into the interior of the main trapping chamber 1.

[0034] In one instance of this embodiment, please refer to Figures 4-9A triangular plate 26 is installed at the lower part of the interior of the insect collection container 24. A pheromone emitter 27 is installed at the upper end of the triangular plate 26, located at the center of the interior of the insect collection container 24. The pheromone emitter 27 contains an attractant, which is either a sex pheromone or a food trap. Insects use their sense of smell to find food, mates, or oviposition sites. Therefore, using artificially synthesized attractants effectively attracts male insects or specific pests, making it easier for insects to crawl into the interior of the insect collection container 24. A ring of air inlets 25 is located at the bottom of the side wall of the insect collection container 24. External air can enter the interior of the insect collection container 24 through the air inlets 25. This facilitates the generation of subsequent airflow loops and allows the insects inside the insect collection container 24 to breathe, thus preventing the insects from dying from lack of oxygen. A scent diffusion hole 36 is provided at the upper end of the main trapping chamber 1. The main trapping chamber 1 is an L-shaped rotary structure. Therefore, a ring of scent diffusion holes 36 is provided on the outer ring of the upper end of the main trapping chamber 1. A ring of upward-curving airflow guide shroud 16 is provided on the lower outer edge of the conical head 15. The airflow generated by the insect scraper blade 11 and the trapping tube 9 flows downward. The airflow flows obliquely downward along the conical surface above the conical head 15. When the airflow comes into contact with the airflow guide shroud 16, the airflow changes direction and becomes upward along the arc surface, so that the airflow finally passes through the scent diffusion hole 36 from bottom to top and flows upward. And because the airflow velocity at the airflow guide shroud 16 is relatively fast, that is, a lower air pressure is formed at this point. At this time, the airflow inside the insect collecting container 24 is relatively high. The relatively high-pressure gas flows upward through the gap between the conical head 15 and the main trapping chamber 1. In other words, the gas mixed with the attractant also flows upward through the odor diffusion hole 36. The outflowing gas diffuses into the external environment, thereby attracting external insects. Since the airflow is upward, the airflow immediately after exiting the odor diffusion hole 36 will surround the outside of the trapping tube 9. At this time, the insects will fly over following the scent and land on the trapping tube 9. As the insects crawl, some of them will crawl into the interior of the trapping tube 9 and be pushed downward by the insect scraper blade 11. At this time, the insects trapped by light and attractant both enter the interior of the main trapping chamber 1, increasing the range of insects that the entire device can trap.

[0035] In one instance of this embodiment, please refer to Figure 6The conical head 15 is hollow, and a motor support plate 22 is installed inside it. A rotary motor 23 is mounted on the motor support plate 22. The output shaft of the rotary motor 23 is fixedly connected to the lower end of the drive shaft 19. The rotary motor 23 drives the insect-scraping blades 11 to rotate, providing air intake and insect-scraping effects. A solar panel can be installed above the insect-attracting device, and a battery can be installed on the motor support plate 22 to drive the rotary motor 23 using solar power. If the lighting conditions are poor or the solar energy storage is insufficient for the rotary motor 23 to operate overnight, an external mains power supply can be connected to the rotary motor 23. The connection of the solar panel or mains power is a conventional technique and is therefore not shown in the attached drawings.

[0036] In one instance of this embodiment, please refer to Figures 7-9 A threaded ring 31 is provided on the upper inner wall of the insect collection container 24, and a threaded sleeve 13 is provided on the lower outer wall of the main trapping chamber 1, so that the insect collection container 24 can be screwed onto the outside of the main trapping chamber 1, achieving a detachable connection. A horizontally extending beam 28 is provided on the upper part of the inner wall of the insect collection container 24. A rotating seat 29 is provided at the end of the extending beam 28 near the center of the insect collection container 24. The rotating seat 29 is rotatably connected to an openable and closable baffle 30. A torsion spring is provided inside the rotating seat 29. The torsion spring can drive the end of the openable and closable baffle 30 near the center of the insect collection container 24 to lift upward, that is, to keep the openable and closable baffle 30 rotating towards a horizontal position. A tubular top pressure ring 14 is provided at the lower part of the inner wall of the main trapping chamber 1. When the insect collection container 24 moves upward, the lower end of the top pressure ring 14 presses against the upper surface of the openable and closable baffle 30. At this time, the top pressure ring... 14. Push the end of the openable baffle 30 near the center of the insect collection container 24 to rotate downwards. After the insect collection container 24 is completely fixed with the main trapping chamber 1, the inner wall of the top pressure ring 14 is in contact with the surface of the openable baffle 30. At this time, the openable baffle 30 is in a vertical state, that is, the top of the insect collection container 24 is open, and insects can freely crawl into the interior of the insect collection container 24. Furthermore, a clearance groove 20 is provided between the main trapping chamber 1 and the top pressure ring 14, so that the end of the openable baffle 30 can extend into the interior of the clearance groove 20, allowing the openable baffle 30 to rotate freely to a vertical state. However, when the insect collection container 24 rotates downwards and disengages from the main trapping chamber 1, the openable and closable baffle 30 can rotate to a horizontal state under the action of the torsion spring inside the rotating seat 29. Multiple openable and closable baffles 30 are evenly distributed on the inner wall of the insect collection container 24. At this time, the horizontal openable and closable baffle 30 can just block the top of the insect collection container 24, thereby preventing the insects stored inside the insect collection container 24 from crawling out of the insect collection container 24.

[0037] In one instance of this embodiment, please refer to Figure 1 , Figure 2 and Figure 10The support frame 35 assembly includes a support frame 35 horizontally disposed outside the main trapping cavity 1. The end of the support frame 35 is rotatably connected to the end of the limiting sleeve 34. The side of the limiting sleeve 34 away from the support frame 35 is slidably connected to the limiting pin 32. The end of the limiting sleeve 34 is an elastic element. The end of the limiting sleeve 34 is threadedly connected to the locking nut 33. When the locking nut 33 is tightened on the outer wall of the limiting sleeve 34, the end of the limiting sleeve 34 can lock the limiting pin 32, thereby locking the extension length of the limiting pin 32. Therefore, when the entire device needs to be set up outdoors, first keep the entire main trapping chamber 1 vertical and place it at a specific height, just above the plants, so that insects can better see the trapping light emitted by the device. At this time, the limiting pins 32 can be pulled out, the three limiting pins 32 can be inserted into the ground, and the locking nut 33 can be tightened. At this time, the total length of the limiting pins 32 and the limiting sleeve 34 is fixed, and the entire main trapping chamber 1 remains vertical for subsequent insect-attracting work.

[0038] In this embodiment, during implementation, an attractant is placed inside the pheromone emitter 27. The pheromone emitter 27 is then rotated upwards onto the lower end of the main trapping chamber 1. At this time, the openable / closeable baffle 30 is pushed vertically by the pressure ring 14, ensuring complete communication between the pheromone emitter 27 and the interior of the main trapping chamber 1. The insect-attracting light column 12 and the rotating motor 23 are then activated. The insect-attracting light column 12 emits light of a specific frequency upwards. When the light comes into contact with the reflector 7 at the bottom of the insect-collecting funnel 6, it is reflected and radiates horizontally outwards. When the light comes into contact with the reflector 7 above the insect-collecting funnel 6... Since the light emitted by the insect-attracting light column 12 is not completely parallel and vertically upward, some of the inclined light rays are reflected by the reflector 7 above and then emitted upward in a radial pattern. This causes the upper part of the entire device to continuously emit insect-attracting light outward. The light-attracting insects will fly towards the device and land on the surface of the trapping conduit 9 or the insect-collecting funnel 6. Since the insect-attracting light column 12 is located inside the trapping conduit 9, the insects will crawl towards the inside of the trapping conduit 9. The insect-scraping paddle 11 will push the insects downward, and eventually the insects will enter the inside of the main trapping chamber 1.

[0039] The rotating insect-scraping blade 11 generates a downward airflow inside the trapping conduit 9. This airflow, guided by the airflow guide shroud 16 inside the main trapping chamber 1, is ultimately discharged through the odor diffusion hole 36. Meanwhile, the pheromone emitter 27 draws in air through the air inlet 25, causing the attractant-laden gas to also diffuse into the environment through the odor diffusion hole 36. Insects attracted by the odor will cling to the outside of the trapping conduit 9. As the insects crawl, they will move into the trapping conduit 9, where the rotating blade 11 will push them further into the main trapping chamber 1. Because the blade 11 continues to rotate, insects inside the main trapping chamber 1 cannot pass through it to escape the trapping conduit 9. Therefore, as the insects crawl through the main trapping chamber 1, they eventually pass through the gap between the conical head 15 and the main trapping chamber 1 and enter the insect collection container 24, thus achieving insect capture.

[0040] After the device has been working for a period of time, the operator unscrews the insect collection container 24 from the lower end of the main trapping chamber 1. As the insect collection container 24 moves down, the openable baffle 30 rotates to a horizontal position. At this time, the openable baffle 30 blocks the top of the insect collection container 24, preventing the insects inside from crawling out. The operator can then manually remove the insects from inside the insect collection container 24 for killing or subsequent research.

[0041] This invention relates to an insect-attracting device. By setting a rotating insect-scraping paddle 11, it can not only actively scrape and transport insects that have crawled into the attracting conduit 9 downwards into the main trapping cavity 1 to prevent them from escaping, but also generate directional airflow through rotation, causing the attractant scent in the pheromone emitter 27 to continuously diffuse from the scent diffusion hole 36, thereby enhancing the range and effect of scent trapping. The entire capture process is completed within a closed system, with no rotating or exposed dangerous parts on the outside of the device, ensuring high safety.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
